- `base_image_filter` (map of strings) - As an alternative to providing `base_image_ocid`,
the user can supply search criteria, and Packer will use the the most recent image that meets
all search criteria. If no image meets all search criteria, Packer returns an error. The
following fields, if specified, must match exactly:
- `compartment_id` - The OCID of the compartment to find the image. If not specified, will use `compartment_ocid`
used for the instance.
- `display_name` - The full name of the image, e.g., `Oracle-Linux-7.8-2020.05.26-0`
- `operating_system` - The operating system used on the image, e.g., `Oracle Linux`
- `operating_system_version` - The version of the operating system on the image, e.g., `7.8`
- `shape` - A shape that the image supports. If not specified, will use `shape` used for the instance
Additionally, the following field takes a regular expression:
- `display_name_search` - a regular expression for the display name, e.g., `^Oracle-Linux`. This
is ignored if `display_name` is also specified under `base_image_filter`. If no images match
the expression, Packer returns an error. If multiple images match, the most recent is used.
`base_image_filter` is ignored if `base_image_ocid` is also specified.
- `compartment_ocid` (string) - The OCID of the

## Base Image Filter Example
Note that `base_image_filter` gets passed as a string, then interpreted as a
regular expression. This means that all back-slashes must be doubled, e.g.,
use `\\w+` to mean `\w+`, and `\\\\` to create the regular expression equivalent
of `\\` (which will search for a literal back-slash).
